In the dual-bearing reel of Patent Document 1, all of the plurality of holes are formed in the main body of the reel of the reel. Therefore, in order to brake the reel as in Patent Document 2, it must be as shown in Patent Document 3. The bottomed cylindrical conductor rotates integrally with the reel. Therefore, even if the hole portion is provided for weight reduction (inertia reduction), the weight (inertia) of the conductor increases, so that it is difficult to brake the reel sufficiently.

The present invention is an invention developed in light of the foregoing problems, and an object thereof is to provide a dual-bearing reel that can reduce the weight of the reel and can appropriately apply a braking force to the reel.

(1) A dual-bearing reel according to an aspect of the present invention includes a reel body, a handle, a reel, and a reel brake. The handle is rotatably installed on the main body of the reel. The reel is provided on the main body of the reel so as to rotate in conjunction with the rotation of the handle. The reel is provided with a winding main body portion and a pair of flange portions. The bobbin main body portion has a perforated cylindrical portion and a non-perforated cylindrical portion. The perforated cylindrical portion has at least one hole portion. The non-perforated cylindrical portion is formed integrally with the perforated cylindrical portion. The pair of flange portions are provided at both ends of the winding main body portion, respectively. The reel braking part is provided on the main body of the reel. The spool braking part can brake the spool by applying at least a magnetic force to the non-porous cylinder part.

In this dual-bearing reel, since the main body portion of the reel has a holed cylindrical portion, the weight of the reel can be reduced. In addition, since the magnetic force of the spool braking portion acts on the non-porous cylinder portion of the spool main body portion, it is possible to appropriately apply a braking force to the spool.

(2) In another aspect of the present invention, a dual-bearing reel, wherein the reel braking portion is provided on the reel body so as to face the inner circumferential surface of the non-perforated cylindrical portion. With this, in addition to the aforementioned effects, it is also possible to reduce the size of the dual-bearing reel.

(3) In another aspect of the present invention, the dual-bearing reel has a rib protruding radially inward on the inner circumferential surface of the holed cylindrical portion. Thereby, even if the hole portion is provided in the holed cylindrical portion, the strength and rigidity of the holed cylindrical portion can be ensured. In addition, even if the hole portion is provided in the holed cylinder portion, the difference in strength and the difference in rigidity between the holed cylinder portion and the non-holed cylinder portion can be reduced. That is, the difference in the amount of deformation between the perforated cylindrical portion and the non-perforated cylindrical portion can be suppressed.

(4) In another aspect of the present invention, a dual-bearing reel, wherein the rib is an annular rib extending in the circumferential direction on the inner peripheral surface of the holed cylindrical portion. With this, the difference in the amount of deformation between the perforated cylindrical portion and the non-perforated cylindrical portion can be more effectively suppressed.

(5) In another aspect of the present invention, in the dual-bearing reel, the inner peripheral surface of the non-perforated cylindrical portion is a large-diameter portion having a small-diameter portion and a large-diameter portion having a small-diameter portion. The reel braking portion is provided on the reel body so as to be able to face the small diameter portion.

In this case, using the boundary between the small-diameter portion and the large-diameter portion of the inner circumferential surface of the non-perforated cylindrical portion as a reference, the roll system acting on the small-diameter portion can be managed The magnetic force of the moving part. That is, the braking force can be appropriately applied to the reel.

(6) In another aspect of the present invention, a dual-bearing reel, wherein the inner peripheral surface of the holed cylindrical portion further has a stepped portion extending in the circumferential direction. The stepped portion connects the small-diameter portion and the large-diameter portion. Even with such a configuration, the same effect as the aforementioned effect can be obtained.

(7) In another aspect of the present invention, in the dual-bearing reel, the small diameter portion is connected to the large diameter portion via a stepped portion, and the large diameter portion is formed continuously with one of the flange portions. Even with such a configuration, the same effects as the aforementioned effects can be obtained.

(8) In another aspect of the present invention, a dual-bearing reel, wherein the reel of the dual-bearing reel has a cylindrical reel main body portion and a pair of flange portions. A fishing line is wound around the outer periphery of the main body of the winding line. A pair of flange portions are provided at both ends of the winding main body portion, respectively.

Here, the bobbin main body portion has a perforated cylindrical portion and a non-perforated cylindrical portion. The perforated cylindrical portion is provided on one side of the pair of flange portions. The holed cylindrical portion has a through hole on the outer periphery. The non-perforated cylindrical portion is provided on the other side of the pair of flange portions. With such a configuration, if the magnetic-type reel braking portion is opposed to the inner peripheral surface of the non-perforated cylindrical portion of the winding main body portion, weight reduction can be achieved, and there is no need to add a bottomed cylindrical conductor. The braking force can be appropriately given.

According to the present invention, the weight of the reel can be reduced, and the braking force can be appropriately applied to the reel.

<Structure of dual bearing reel>

Fig. 1 shows a dual-bearing reel used in an embodiment of the present invention. As shown in FIGS. 1 and 2, the dual-bearing reel includes a reel body 1, a handle 3, a reel 5, and a reel brake mechanism 7.

In the following, the direction in which the fishing line is repeatedly fed forward is referred to as [front], and the direction opposite to the direction in which the fishing line is repeatedly fed forward is referred to as [rear]. In addition, the side where the reel body 1 is installed on the fishing rod may be referred to as "downward", and the direction opposite to the side where the reel body 1 is installed on the fishing rod may be referred to as "upper".

In addition, the direction in which the spool shaft 16 extends, the direction in which the pinion gear 36 extends, and the direction in which the screw shaft 23 extends are substantially the same direction. Therefore, these directions may be referred to as "axis directions" in the following description. In addition, the spool shaft 16, the pinion gear 36, and the screw shaft 23 will be described later.

[Reel body]

As shown in FIG. 2, the reel body 1 includes a frame 4, a first side cover 9 and a second side cover 11, and a thumb seat 13 mounted on the upper portion of the frame 4 (see FIG. 1 ).

The frame 4 has a first side plate 15, a second side plate 17, and a plurality of connecting portions (not shown). The first side plate 15 and the second side plate 17 are arranged to face each other at a predetermined interval. In detail, the first side plate 15 is provided on the side opposite to the handle 3, and the second side plate 17 is provided on the handle 3 side. The first side plate 15 and the second side plate 17 are formed with openings 15a and 17a where the reel 5 can be placed. The plurality of connecting portions connect the first side plate 15 and the second side plate 17.

A brake case 19 is fixed to the opening 15a. The brake case 19 is a bottomed cylindrical box member. The brake case 19 is installed in the opening 15a of the first side plate 15 by, for example, a screw-in structure. In addition, in the opening 15a, a reel brake mechanism 7 for suppressing backlash at the time of throwing is disposed via the brake case 19.

The first side cover 9 is attached to the side opposite to the handle 3, and is attached to, for example, the first side plate 15 of the frame 4. The second side cover 11 is attached to the handle 3 side, and is detachably attached to, for example, the second side plate 17 of the frame 4. Between the first side cover 9 and the brake case 19, an operation for operating the drum brake mechanism 7 is arranged Make knob 63.

In the frame 4, the reel 5, the uniform winding mechanism 21 and the clutch operating lever 26 are arranged.

The uniform line winding mechanism 21 is a mechanism for evenly winding the fishing line around the reel 5. The uniform winding mechanism 21 has a guide cylinder 22, a screw shaft 23, and a wire guide 24. The guide cylinder 22 guides the wire guide 24 in the axial direction. The guide tube 22 is fixed between the first side plate 15 and the second side plate 17. The screw shaft 23 is rotatably arranged in the guide cylinder 22. A spiral groove is formed in the screw shaft 23, and the wire guide 24 is engaged with the spiral groove.

With this structure, when the screw shaft 23 is rotated by the gear mechanism 25 (described later), the wire guide 24 reciprocates along the guide cylinder 22. As a result, the fishing line inserted through the line guide 24 is evenly wound on the reel 5.

The clutch operating lever 26 is arranged behind the reel 5 between the first side plate 15 and the second side plate 17. The clutch operating lever 26 is configured to be slidable in the vertical direction. The clutch operating lever 26 can actuate the clutch disengagement mechanism 27 (described later) via a clutch cam (not shown).

Between the frame 4 and the second side cover 11, a gear mechanism 25; a clutch disengagement mechanism 27; a clutch mechanism 29; a drag mechanism 31; and a throwing control mechanism 33 are arranged.

The gear mechanism 25 transmits the rotational force from the handle 3 to the reel 5 and the uniform winding mechanism 21. The gear mechanism 25 has a drive gear 35, a pinion gear 36, a first gear 37, and a second gear 38.

The driving gear 35 can rotate integrally with the driving shaft 30 and can It is installed in relative rotation. In detail, the drive gear 35 can rotate integrally or relatively rotate the drive shaft 30 by the drag mechanism 31. The pinion gear 36 is rotatably supported by the second side plate 17. The pinion 36 is attached to the spool shaft 16 so as to be free to move in the axial direction. The pinion gear 36 is formed substantially in a cylindrical shape. A spool shaft 16 is inserted through the center of the pinion gear 36.

The pinion gear 36 meshes with the drive gear 35. The first gear 37 is fixed to the end of the screw shaft 23. The second gear 38 is rotatably fixed to the drive shaft 30 and meshes with the first gear 37. With this structure, when the drive shaft 30 rotates, the first gear 37 meshed with the second gear 38 rotates. Then, by the rotation of the first gear 37, the screw shaft 23 also rotates. As a result, the uniform winding mechanism 21 operates as described above.

The clutch disengagement mechanism 27 disengages (engages and disengages) the clutch mechanism 29 in response to the operation of the clutch operating lever 26. The clutch disengagement mechanism 27 has a clutch yoke 39. The clutch disengagement mechanism 27 moves the clutch yoke 39 parallel to the axis of the spool shaft 16 by the operation of the clutch operating lever 26. Thereby, the clutch mechanism 29 is closed, so that the reel 5 can rotate freely. In addition, the clutch disengagement mechanism 27 moves the clutch yoke 39 so that when the drive shaft 30 rotates in the fishing line winding direction, the clutch mechanism 29 automatically opens.

The clutch mechanism 29 is used to connect the drive shaft 30 and the spool shaft 16 and to disconnect the drive shaft 30 and the spool shaft 16. The clutch mechanism 29 is composed of an engagement portion 36b of the pinion gear 36 and a clutch pin 16a penetrating the spool shaft 16 in the radial direction.

Here, the pinion gear 36 has a tooth portion 36a and a meshing portion 36b And the diameter reducing portion 36c. The tooth portion 36 a is provided at one end of the pinion gear 36 and meshes with the drive gear 35. The meshing portion 36b is provided at the other end portion of the pinion gear 36. In the meshing portion 36b, a recessed portion that can be engaged with the clutch pin 16a is formed. The reduced diameter portion 36c is provided between the tooth portion 36a and the meshing portion 36b. The clutch yoke 39 of the clutch disengagement mechanism 27 is engaged with the reduced diameter portion 36c.

The clutch pin 16a is a concave portion that engages with the meshing portion 36b. For example, when the pinion 36 is moved along the spool shaft 16 by the clutch yoke 39 of the clutch disengagement mechanism 27, the concave portion of the engaging portion 36b is from the clutch pin 16a. As a result, the coupling between the drive shaft 30 and the spool shaft 16 is released. In this case, the rotation from the drive shaft 30 is not transmitted to the reel 5. That is, this state is the state where the clutch is off.

In addition, when the drive shaft 30 rotates in the fishing line winding direction, the clutch pin 16a is engaged with the concave portion of the engaging portion 36b. As a result, the drive shaft 30 and the spool shaft 16 are connected. In this case, the rotation from the drive shaft 30 is transmitted to the reel 5. That is, this state is the state where the clutch is on. Furthermore, the general state is the state where the clutch is on.

The towing mechanism 31 brakes the reel 5 when the fishing line is repeatedly sent out. In detail, when the fishing line is pulled with a force exceeding the towing force, the towing mechanism 31 is activated, and the reel 5 rotates in the direction in which the fishing line is repeatedly fed out.

The towing mechanism 31 has a star-shaped fishing force valve 32 and a friction mechanism 34. The star-shaped fishing force valve 32 is a mechanism for adjusting the drag force. In detail, by rotating the star-shaped fishing force valve 32, the pressing state of the friction mechanism 34 is changed, and the drag force is adjusted.

The friction mechanism 34 is composed of a plurality of brake plates. friction The mechanism 34 is arranged between the one-way clutch 43 and the drive gear 35. For example, when the fishing line is pulled with a force exceeding the drag force, and the reel 5 rotates in the direction in which the fishing line is repeatedly fed out, the drag mechanism 34 is activated, and the drive gear 35 relatively rotates the drive shaft 30.

The throwing control mechanism 33 is used to brake the spool 5 by holding both ends of the spool shaft 16. The throwing control mechanism 33 includes a cover 40, a first friction plate 41, a second friction plate 42, and the first friction plate 41 and the second friction plate 42 are in contact with both ends of the spool shaft 16 to pinch the spool shaft 16. For example, when the cover 40 has rotated, the holding force of holding the spool shaft 16 by the first friction plate 41 and the second friction plate 42 is adjusted. With this, the braking force of the reel 5 is adjusted.

〔handle〕

The handle 3 is rotatably provided on the reel body 1. In detail, as shown in FIGS. 1 and 2, the handle 3 is disposed on the side of the reel body 1 and is rotatably attached to the reel body 1. In the handle 3, the drive shaft 30 is rotatably installed integrally. The drive shaft 30 is rotatably supported by the second side plate 17 and the second side cover. Here, the drive shaft 30 is rotatably supported by the second side plate 17 via a bearing, and is rotatably supported by the second side cover via a one-way clutch 43. The one-way clutch 43 restricts the rotation of the drive shaft 30 in the direction in which the fishing line is repeatedly fed out, and permits the rotation of the drive shaft 30 in the fishing line winding direction. The one-way clutch 43 is installed on the second side cover 11 and supports the drive shaft 30. In this case, the rotation of the handle 3, that is, the rotation of the drive shaft 30 is transmitted to the drive gear 35 via the one-way clutch 43 and the drag mechanism 31, This causes the reel 5 to rotate.

〔reel〕

The reel 5 is a non-magnetic conductor made of aluminum alloy, for example. As shown in FIGS. 1 and 2, the reel 5 is provided on the reel body 1 so as to be able to rotate in conjunction with the rotation of the handle 3. As shown in FIG. 3, the reel 5 has a winding main body 51, a pair of first flange parts 59 and an installation part 61.

In the following description, one of the pair of flange portions 59, for example, the flange portion on the handle 3 side may be referred to as a first flange portion 59a. In addition, the other of the pair of flange portions 59, for example, the flange portion on the opposite side of the handle 3 may be referred to as a second flange portion 59b.

A fishing line is wound around the outer periphery of the reel main body 51. The winding main body portion 51 is formed substantially in a cylindrical shape. The bobbin main body portion 51 has a perforated cylindrical portion 52 and a non-perforated cylindrical portion 53.

The perforated cylindrical portion 52 is a part that contributes to weight reduction (reduction of inertia) of the reel 5. The perforated cylindrical portion 52 is provided at least on the first flange portion 59a side. Here, as shown in FIG. 3, the perforated cylindrical portion 52 is composed of the vicinity of the first flange portion 59a and the central portion between the axial direction of the first flange portion 59a and the second flange portion 59b.

Specifically, the perforated cylindrical portion 52 has a first body portion 54, a plurality of hole portions 54a, and rib portions 54b. The first body portion 54 is formed substantially in a cylindrical shape. The first body portion 54 is a winding main body portion 51 on which the handle 3 is formed. The first body portion 54 is integrally formed on the first flange portion 59a, and is integrally formed on the second body portion 55 of the non-perforated cylindrical portion 53 (Described later).

A fishing line is wound around the outer peripheral surface of the first body 54. The inner peripheral surface of the first body portion 54 is the inner peripheral surface of the second body portion 55 connected to the non-perforated cylindrical portion 53. That is, the inner peripheral surface of the first body portion 54 is formed continuously with the inner peripheral surface of the second body portion 55. In addition, the inner peripheral surface of the first body portion 54 is continuously connected to the outer surface of the first flange portion 59a.

The plurality of hole portions 54a are through holes that penetrate the first body portion 54 from the inner peripheral surface to the outer peripheral surface. That is, each of the plurality of hole portions 54a is a through hole penetrating in the radial direction. The plurality of hole portions 54a are provided in the first body portion 54. Specifically, a plurality of hole portions 54a are tied in the axial direction, and are formed in the first area from the center portion between the first flange portion 59a and the second flange portion 59b to the first flange portion 59a. The circumferential direction of the main body 54. In other words, a plurality of hole portions 54a are formed on both sides of the mesh portion 61b (described later) of the mounting portion 61, radially outward of the mesh portion 61b of the mounting portion 61, and near the first flange portion 59a, and are formed in the first body Part 54 in the circumferential direction.

In addition, the range of the perforated cylindrical portion 52 (first body portion 54) corresponds to the range in which a plurality of hole portions 54a are provided. In detail, the boundary between the perforated cylindrical portion 52 and the non-perforated cylindrical portion 53 is defined by the inner peripheral surface of the hole portion 54a farthest from the first flange portion 59a. In Fig. 3, this boundary is shown with a dotted line.

The rib 54b is provided on the inner circumferential surface of the holed cylindrical portion 52. Here, the rib 54b is formed in a ring shape. Specifically, the rib portion 54b is arranged between the hole portions 54a adjacent in the axial direction. The rib 54b extends radially inward from the inner circumferential surface of the perforated cylindrical portion 52, for example, the first body portion 54 The side protrudes so as to be formed on the first body 54. In addition, the rib 54 b is formed on the first body 54 so as to extend in the circumferential direction on the inner peripheral surface of the first body 54.

The non-perforated cylindrical portion 53 is a portion that is braked by the magnetic force of the reel brake mechanism 7. As shown in FIGS. 3 and 4, the non-perforated cylindrical portion 53 is provided on the side of the second flange portion 59b.

Specifically, the non-perforated cylindrical portion 53 has a second body portion 55, a small-diameter portion 56, a large-diameter portion 57, and a stepped portion 58. The second body portion 55 is formed substantially in a cylindrical shape. The second body portion 55 is formed with a winding main body portion 51 opposite to the handle 3. The second body portion 55 is formed integrally with the first body portion 54 and is formed integrally with the second flange portion 59b.

On the outer peripheral surface of the second body portion 55, a fishing line is wound. That is, the outer peripheral surface of the winding main body portion 51 is formed by the outer peripheral surface of the first body portion 54 and the outer peripheral surface of the second body portion 55. The inner peripheral surface of the second body portion 55 is the inner peripheral surface of the first body portion 54 connected to the holed cylindrical portion 52. That is, the inner peripheral surface of the second body portion 55 is formed continuously with the inner peripheral surface of the first body portion 54.

Specifically, the inner peripheral surface of the second body portion 55 is composed of the small-diameter portion 56, the large-diameter portion 57, and the stepped portion 58. The small-diameter portion 56 forms an inner peripheral surface of the second body portion 55. The small-diameter portion 56 is connected to the large-diameter portion 57 via a stepped portion 58. In addition, the small-diameter portion 56 is connected to the inner peripheral surface of the first body portion 54. Here, the inner diameter of the small-diameter portion 56 is the same as the inner diameter of the first body portion 54.

The spool brake mechanism 7 may face the small-diameter portion 56. in Here, the corner portion P formed by the small diameter portion 56 and the stepped portion 58 is used as a reference for managing the magnetic force of the spool brake mechanism 7 acting on the small diameter portion 56.

For example, the corner portion P extends in the circumferential direction on the small-diameter portion 56 which is the inner peripheral surface of the winding main body portion 51. With this corner portion P, the reference line of the small-diameter portion 56 of the inner peripheral surface of the winding main body portion 51 is defined. Here, the small diameter portion 56 is formed with the same diameter in the axial direction. Therefore, using the corner portion P as a reference, the area through which the magnetic flux passes on the small-diameter portion 56 (magnetic flux passing area) can be easily managed. For example, since the passage area of the magnetic flux is based on the corner portion P and increases in accordance with the axial length of the small-diameter portion 56, the change of the braking force on the reel 5 can be stabilized.

In addition, when the corner portion P is not provided on the inner peripheral surface of the winding main body portion 51, it is difficult to define the reference of the small-diameter portion 56. In this case, for example, bent portions are provided on both end sides of the inner peripheral surface of the winding main body portion 51. In addition, the same diameter portion is provided between the bent portions at both ends. In this structure, when the curved portion is formed, there is a possibility that the position of the boundary between the curved portion and the same-diameter portion is uneven in the axial direction. As a result, the passage area of the magnetic flux of the same-diameter portion is less stable than when the corner portion P is provided. That is, it is not easy to stabilize the change of the braking force on the reel 5.

In addition, the large-diameter portion 57 is formed to have a smaller-diameter portion 56 and a larger diameter. The large-diameter portion 57 forms an inner peripheral surface of the second body portion 55. The large diameter portion 57 is connected to the large diameter portion 56 via a stepped portion 58. The large diameter portion 57 is continuously connected to the outer surface of the second flange portion 59b.

The stepped portion 58 connects the small diameter portion 56 and the large diameter portion 57 Location. The stepped portion 58 extends in the circumferential direction, and an inner circumferential surface of the second body portion 55 is formed between the small-diameter portion 56 and the large-diameter portion 57. In detail, the stepped portion 58 is an inner circumferential surface that enlarges the diameter from the small diameter portion 56 toward the large diameter portion 57 and forms the second body portion 55.

As shown in FIG. 3, the first and second flange portions 59a and 59b are formed substantially in a disk shape. The first and second flange portions 59a and 59b are respectively provided at both end portions of the winding main body portion 51. In detail, the first and second flange portions 59 a and 59 b are integrally formed at the end of the reel body 51 so as to extend radially outward from the end of the reel body 51. In addition, here, the curved surface including the outer peripheral surface of the winding main body portion 51 and the portion radially outward of the curved surface are collectively defined as the first and second flange portions 59a and 59b. In FIG. 4, the boundary between the first and second flange portions 59 a and 59 b and the winding main body portion 51 is shown by broken lines.

As shown in FIG. 3, the installation portion 61 has a hub portion 61a and a mesh portion 61b. The hub 61a is formed substantially in a cylindrical shape. The hub 61a is attached to the spool shaft 16. In detail, the hub portion 61a is fixed to the spool shaft 16 by a fixing means such as zigzag and non-rotatably fixed. The net portion 61b is formed substantially in a ring shape. The net portion 61b connects the hub portion 61a and the winding main body portion 51. In detail, the net portion 61b is integrally formed on the outer peripheral surface of the hub portion 61a and the inner peripheral surface of the winding main body portion 51.

As shown in FIGS. 2 and 3, the spool shaft 16 is installed on the spool 5 so as to be rotatable integrally with the spool 5. The spool shaft 16 penetrates the second side plate 17 and extends toward the second side cover 11. One end of the spool shaft 16 is rotatably supported by the second side cover 11 via a bearing. Also, the reel shaft 16 The other end is rotatably supported by the brake case 19 via a bearing. Furthermore, as described above, the spool shaft 16 is fixed to the spool 5 (the hub portion 61a of the installation portion 61) between one end and the other end. With this, the spool shaft 16 rotates together with the spool 5.

〔Reel brake mechanism〕

The reel brake mechanism 7 can use magnetic force to brake the reel 5. In detail, the spool brake mechanism 7 applies force to the spool 5 in the direction of rotation of the spool 5 and the opposite direction to brake the spool 5. Here, the spool braking mechanism 7 applies a force in the rotation direction of the spool 5 and the opposite direction to at least the non-perforated cylinder portion 53 of the spool 5 to brake the spool 5.

As shown in FIG. 2, the reel brake mechanism 7 is provided on the reel body 1. In detail, as shown in FIGS. 5 and 6, the spool brake mechanism 7 is provided on the reel body 1 via the brake box 19.

An operation knob 63 (described later) for operating the spool brake mechanism 7 is engaged with a plurality of through holes 19b.

As shown in FIGS. 5 to 7, the spool brake mechanism 7 includes a magnetic body 71, a cylindrical first cylindrical portion 73, a cylindrical second cylindrical portion 75, a spring member 77, and a release prevention member 79. In this case, the spool braking mechanism 7 may be regarded as an example of the spool braking portion, or the magnetic body 71 may be regarded as an example of the spool braking portion.

The magnetic body 71 is made by applying a magnetic force to the reel 5 The rotation of the moving drum 5. The magnetic body 71 is composed of, for example, a plurality of magnets 71a. As the plurality of magnets 71a, for example, permanent magnets can be used.

A plurality of magnets 71a are fixed to the outer peripheral portion of the second cylindrical portion 75. Here, the plurality of magnets 71a are fixed to the outer peripheral portion of the second cylindrical portion 75 at predetermined intervals in the circumferential direction.

As shown in FIGS. 4 to 6, the plurality of magnets 71 a are provided so as to be able to face the inner circumferential surface of the winding main body portion 51 in the reel 5. In detail, the plurality of magnets 71a are provided so as to be able to face the inner peripheral surface of the non-perforated cylindrical portion 53 of the winding main body portion 51. In more detail, the plurality of magnets 71a are provided so as to be able to face the small-diameter portion 56 of the non-perforated cylindrical portion 53.

As shown in FIGS. 5 and 6, the first cylindrical portion 73 is an outer peripheral portion of the cylindrical portion 19 a of the brake case 19. In detail, the inner peripheral portion of the first cylindrical portion 73 is attached to the outer peripheral portion of the cylindrical portion 19a of the brake case 19. Specifically, as shown in FIG. 7, the first cylindrical portion 73 has an engaged portion 73a. The engaged portion 73a is engaged with the engaging portion 75a (described later) of the second cylindrical portion 75. For example, the engaged portion 73a is formed into a concave shape.

As shown in FIGS. 5 and 6, the second cylindrical portion 75 is installed on the outer peripheral portion of the first cylindrical portion 73. In detail, the second cylindrical portion 75 is attached to the outer peripheral portion of the first cylindrical portion 73 so as to be relatively rotatable and movable in the axial direction. Specifically, as shown in FIG. 7, the second cylindrical portion 75 has an engaging portion 75a. The engaging portion 75a is provided on the inner peripheral portion of the second cylindrical portion 75. The engaging portion 75a is guided by the engaged portion 73a formed in the first cylindrical portion 73. In detail, when the engaging portion 75a engages and moves the engaged portion 73a, the second cylindrical portion 75 and the plurality of magnets 71a rotate relative to the first cylindrical portion 73 Turn and move towards the axis.

As shown in FIGS. 5 to 7, the spring member 77 is a member for elastically pushing the second cylindrical portion 75. Specifically, the spring member 77 urges the second cylindrical portion 75 toward the brake case 19 side (left side in FIGS. 5 and 6 ). The spring member 77 is disposed between the fall prevention member 79 and the second cylindrical portion 75. The spring member 77 is fine, for example, a conical coil spring. The spring member 77 is formed of a non-magnetic material such as SUS303 so as not to be attracted by the magnet 71a.

The detachment prevention member 79 is a member for preventing the spring member 77 from falling off. The fall prevention member 79 is attached to the first cylindrical portion 73. Specifically, the screw-off prevention member 79 is attached to the first cylindrical portion 73 by screwing the male screw portion of the screw-off prevention member 79 to the female screw portion of the first cylinder portion 73.

In such a reel braking mechanism 7, the braking force of the reel 5 is adjusted in response to the rotation of the reel 5. Specifically, in a state where the plurality of magnets 71a and the winding main body portion 51 (the small-diameter portion 56 of the non-perforated cylindrical portion 53) of the spool 5 face each other in the radial direction, the spool 5 rotates depending on the spool The number of rotations (rotation speed) of 5 adjusts the braking force of the reel 5.

Specifically, when the spool 5 has been placed in the magnetic field of the magnet 71a and the spool 5 rotates, an eddy current according to the number of rotations of the spool 5 is generated. The eddy current is generated to give the spool 5 a force in the direction opposite to the direction of rotation. With this, the reel 5 is braked in accordance with the rotation speed.

Then, the reaction force corresponding to the braking force of the reel 5 acts on the second barrel portion 75. By this reaction force, the second cylindrical portion 75 rotates the first cylindrical portion 73. In response to the amount of rotation of the second cylindrical portion 75, it engages The portion 75a moves along the engaged portion 73a. Then, the second cylindrical portion 75 and the plurality of magnets 71a move in the axial direction while rotating the first cylindrical portion 73.

Thereby, the opposing area of the winding main body portion 51 (small diameter portion 56 of the non-perforated cylindrical portion 53) of the spool 5 and the magnet 71a changes, and the braking force of the spool 5 changes. Furthermore, the opposing range corresponds to the area of the portion of the winding main body portion 51 (small diameter portion 56 of the non-perforated cylindrical portion 53) of the winding drum 5 facing the magnet 71a in the radial direction.

The operation knob 63 is a member for setting the initial braking force of the reel 5. As shown in FIGS. 5 and 6, the operation knob 63 has a circular knob portion 63 a and a plurality of pressing portions 63 b. The knob portion 63a is exposed from the opening 9a formed in the first side cover 9. A plurality of pressing portions 63b respectively protrude from the knob portion 63a. The plurality of pressing portions 63b are inserted into the through-holes 19b, abut on the first cylindrical portion 73, and can press the first cylindrical portion 73.

The knob portion 63a is rotatably supported by the opening 9a. The knob portion 63a includes a cam mechanism (not shown) that converts the rotation of the knob portion 63a into axial movement of the pressing portion 63b. As a result, when the knob portion 63a is rotated clockwise, the first cylindrical portion 73 is pressed by the pressing portion 63b, so that the first cylindrical portion 73, the second cylindrical portion 75, and the magnet 71a are oriented in the axial direction of the reel 5 (FIG. Right side of 3) Move. As a result, the number of magnetic fluxes passing through the spool 5 increases, and the initial braking force on the spool 5 becomes stronger.

In addition, when the knob portion 63a rotates in the counterclockwise direction, the first cylindrical portion 73, the second cylindrical portion 75, and the magnet 71a move in the axial direction (left side in FIG. 3) to be separated from the reel 5. As a result, the number of magnetic fluxes passing through the reel 5 Reduced, the initial braking force on the reel 5 becomes weak.

<Operation of dual bearing reel>

Here, the operation of the reel will be described. In the normal state, the clutch yoke 39 is pushed inward, and the clutch is open. As a result, the rotational force from the handle 3 is transmitted to the spool 5 via the drive shaft 30, the drive gear 35, the pinion gear 36, and the spool shaft 16. That is, when the handle 3 is rotated, the reel 5 rotates in the fishing line winding direction.

In the case of throwing, in order to suppress backlash, the operation knob 63 is rotated to adjust the initial braking force. When it is desired to suppress the entire braking force, it is sufficient to rotate the operation knob 63 in the counterclockwise direction to move the magnet 71a away from the reel 5. When the operation knob 63 is rotated in the counterclockwise direction, the magnet 71a moves in the direction of separation from the reel 5 by the action of the cam. As a result, the number of magnetic fluxes passing through the spool 5 is reduced, so that the overall braking force becomes weak.

In addition, when it is desired to increase the overall braking force, it is sufficient to rotate the operation knob 63 clockwise to bring the magnet 71a close to the reel 5. When the operation knob 63 is rotated in the clockwise direction, the magnet 71a moves in the direction of receiving the reel 5 by the action of the cam. As a result, the number of magnetic fluxes passing through the reel 5 increases, so that the overall braking force becomes stronger.

Next, when the clutch operating lever 26 is pressed downward, the clutch yoke 39 moves toward the handle 3 by the movement of the clutch operating lever 26, and the pinion 36 also moves in the same direction. As a result, the clutch is closed. In this clutch off state, the The rotation is not transmitted to the spool 5 and the spool shaft 16, and the spool 5 can rotate freely. In the clutch-off state, when the reel is pressed with the thumb and the reel is tilted in the axial direction so that the reel shaft 16 swings the fishing rod along the vertical plane, the bait is thrown out, and the reel 5 rotates in the direction in which the fishing line is repeatedly fed out.

When a plurality of magnets 71a are opposed to the winding main body portion 51 (small diameter portion 56 of the non-perforated cylindrical portion 53) of the spool 5, the braking force acts on the spool 5 when the spool 5 rotates. In this way, in the state where the reel 5 is braked, the reaction force in response to the braking force acts on the second barrel portion 75. Then, when the second cylindrical portion 75 is rotated by this reaction force, the engaging portion 75a is guided and moved by the engaged portion 73a. Then, the second cylindrical portion 75 and the magnet 71a move in the axial direction toward the handle 3 side (right side in FIG. 4).

Here, when the rotation number (rotation speed) of the spool 5 increases, the reaction force corresponding to the braking force also increases. Then, the second cylindrical portion 75 and the magnet 71a move toward the inner peripheral portion of the winding main body portion 51 of the reel 5. As a result, the number of magnetic fluxes acting on the spool 5 increases, so that the braking force on the spool 5 becomes stronger. In addition, as the number of rotations (rotation speed) of the spool 5 decreases, the reaction force corresponding to the braking force becomes smaller. Then, the second cylindrical portion 75 and the magnet 71a are moved in the axial direction by the spring member 77 to be away from the handle 3. As a result, the number of magnetic fluxes acting on the spool 5 is reduced, so that the braking force on the spool 5 is weakened. In this way, the braking force of the spool 5 is automatically adjusted in response to the rotation of the spool 5.
